Consider the following scenario:
You have an acquaintance, who would probably be really good at turncoat (the game in which one person has to rapidly switch sides again and again on a topic). Whenever you bring up any topic for conversation, their prime goal is to contradict you and prove you wrong, regardless of their opinion on the matter.
For example, consider the following two hypothetical conversations:
You: Did you hear of Hyperloop, designed by Elon Musk? Sounds promising, don't you think?
Them: Are you kidding me? That sort of technology has been proven to be infeasible by scientists at MIT!
You: Have you heard of Hyperloop? Far-fetched, don't you think?
Them: Far-fetched? For your information, Elon Musk has already started trials of the prototype!
You get the point.They always want to 'prove' you wrong, regardless of whether the 'facts' they quote are accurate or not. In the hypothetical conversations stated above, they could easily pick either side of the argument and go on to 'prove' they're right!
If their arguments are weak (consider case 1), you often debate with them and defeat them, but it gives little satisfaction as they just smirk. Plus, you're a pacifist and don't like arguing.
How would you deal with this irritating habit of your acquaintance?
Thanks everyone, I found all your answers very helpful! They certainly have helped me deal with such situations better!
